Write operations
Write operations for one or more bytes
A write is first performed to load the base register address into the Address Counter without
sending a Stop condition. After the bus master receives an acknowledgement from the
slave device, it may start to send a data byte to the register (pointed by the Address
Counter). The slave device again acknowledges and the bus master terminates the transfer
with a Stop condition.
If the bus master would like to continue to write more data, it can just continue write
operation without issuing the Stop condition. After the bus master writes the last data byte
and the slave device acknowledges the receipt of the last data, the bus master may
terminate the write operation by sending a Stop condition. When the Address Counter
reaches the last memory address, it 'rolls-over' on the next data byte write.
